KANSAS CITY, Mo. -- Inergy, L.P. (NASDAQ:NRGY) and Inergy Holdings, L.P. (NASDAQ:NRGP) today each reported results of operations for the quarter and fiscal year ended September 30, 2006.

Inergy, L.P.

Inergy, L.P. (Inergy) reported Adjusted EBITDA of $175.4 million for the year ended September 30, 2006, an increase of approximately 57.3% from $111.5 million for the year ended September 30, 2005. Distributable cash flow per unit on a fully distributed basis increased approximately 13.4% to $2.28 per diluted limited partner unit in 2006 from $2.01 per diluted limited partner unit in 2005. Distributable cash flow was $119.4 million in fiscal 2006 compared to $75.4 million in fiscal 2005.

Net income excluding certain items was $41.2 million for the year ended September 30, 2006, or $0.55 per diluted limited partner unit (exclusions include the recognition of $20.0 million of non-cash charges from derivative contracts associated with retail propane fixed price sales which previously resulted in mark-to-market, non-cash gains in fiscal 2005 and a loss of $11.4 million on the disposal of excess property, plant and equipment). Net income for fiscal 2005 was $26.9 million or $0.60 per diluted limited partner unit (excluding the $19.4 million non-cash gain associated with derivative contracts, a $7.0 million net charge to earnings associated with the early retirement of debt in December 2004, and a $0.7 million loss on the disposal of excess property, plant and equipment).

As previously announced, the Board of Directors of Inergy's general partner increased Inergy's quarterly cash distribution to $0.555 per limited partner unit ($2.22 annually) for the quarter ended September 30, 2006. This represents an approximate 6.7% increase over the distribution for the same quarter of the prior year. The distribution was paid on November 14, 2006.

"These outstanding fiscal 2006 results speak for themselves in that we achieved our financial objectives on behalf of our unitholders despite facing a challenging operating environment," said John Sherman, President and CEO of Inergy. "This performance also represents the first full fiscal year of contribution from a series of strategic acquisitions including Star Gas, Moulton, Northwest and Dowdle Propane as well as the Stagecoach natural gas storage facility."

For fiscal 2006, Inergy closed ten acquisitions. All of the acquisitions are expected to be accretive on a distributable cash flow per unit basis.

"Looking forward to fiscal 2007, Inergy is well positioned to continue to consolidate the highly fragmented propane industry and invest significant capital in high return, organic growth projects in our midstream segment," said Mr. Sherman.

Inergy also reiterates its previously announced earnings guidance for the full fiscal year ended September 30, 2007. Below is a table reconciling forecasted Adjusted EBITDA to net income:

This press release contains forward-looking statements, which are statements that are not historical in nature such as our business outlook. Forward-looking statements are subject to certain risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or any underlying assumption proves incorrect, actual results may vary materially from those anticipated, estimated or projected. Among the key factors that could cause actual results to differ materially from those referred to in the forward-looking statements are: weather conditions that vary significantly from historically normal conditions, the general level of petroleum product demand and the availability of propane supplies, the price of propane to the consumer compared to the price of alternative and competing fuels, the demand for high deliverability natural gas storage capacity in the Northeast, our ability to successfully implement our business plan, the outcome of rate decisions levied by the Federal Energy Regulatory Commission, our ability to generate available cash for distribution to unitholders, and the costs and effects of legal, regulatory and administrative proceedings against us or which may be brought against us. These and other risks and assumptions are described in Inergy's annual reports on Form 10-K and other reports that are available from the United States Securities and Exchange Commission.

(a) EBITDA is defined as income (loss) before taxes, plus net interest expense (inclusive of write-off of deferred financing costs) and depreciation and amortization expense. Adjusted EBITDA represents EBITDA excluding (1) non-cash gains or losses on derivative contracts associated with fixed price sales to retail propane customers, (2) long-term incentive (one-time conversion bonuses) and equity compensation expense and (3) gains or losses on disposal of property, plant and equipment. EBITDA and Adjusted EBITDA should not be considered an alternative to net income, income before income taxes, cash flows from operating activities, or any other measure of financial performance calculated in accordance with generally accepted accounting principles as those items are used to measure operating performance, liquidity or ability to service debt obligations. EBITDA and Adjusted EBITDA are presented because such information is relevant and is used by management, industry analysts, investors, lenders and rating agencies to assess the financial performance and operating results of our fundamental business activities. We believe that the presentation of EBITDA and Adjusted EBITDA is useful to lenders and investors because of their use in the propane industry and for master limited partnerships as an indicator of the strength and performance of the ongoing business operations, including the ability to fund capital expenditures, service debt and pay distributions. Additionally, we believe that EBITDA and Adjusted EBITDA provide useful information to our investors for trending, analyzing and benchmarking our operating results as compared to other companies that may have different financing and capital structures. The presentation of EBITDA and Adjusted EBITDA allow investors to view our performance in a manner similar to the methods used by management and provide additional insight to our operating results.

(b) Cash interest expense is net of amortization charges associated with deferred financing costs. Write-off of deferred financing costs for the year ended September 30, 2005 includes $1.5 million from the early retirement of a bank credit facility and $5.5 million associated with the incurrence and write-off in December 2004 of commitment and funding fees associated with the bridge financing facility utilized in the Star Gas Propane, L.P. acquisition.

(c) Maintenance capital expenditures are defined as those capital expenditures which do not increase operating capacity or revenues from existing levels.

(d) Distributable cash flow is defined as Adjusted EBITDA, less cash interest expense, maintenance capital expenditures and income taxes. We believe that distributable cash flow provides additional information for evaluating Inergy's ability to declare and pay distributions to unitholders. Distributable cash flow should not be considered an alternative to cash flow from operating activities or any other measure of financial performance in accordance with accounting principles generally accepted in the United States. Distributable cash flow, as we define it, may not be comparable to distributable cash flow or similarly titled measures used by other corporations and partnerships.
